Answer:
Sheave wheel and hoist cable
Explanation:
The sheave wheel is a pulley wheel that sits above the mine shaft. The hoist cable passes over the sheave wheel and then down the shaft of the mine. The sheave wheel reduces the sliding friction of the mine cable. The head frame is the structure that supports the sheave wheel.
Answer:
(c) system.exist(1);
Explanation:
system.exist(1); is used for the termination of the program here both option c and d should be correct but in option d there is exit(0) and zero indicates return means program will return but besides zero if there is any non zero number then program will not return and in option c there is a non zero number which means program will not return so option c system.exist(1); will be the correct option for the termination of program
// this function will return 1 if the string sent in arguments is palindrome //else it will return 0
int palindrome(int start_of_string, int end_of_string, string &strr)
{
// base case to check if the string is not empty
if (start_of_string>= end_of_string)
return 1;
if (strr[start_of_string] != strr[end_of_string])
return 0;
// recursive call
return palindrome(++start_of_string, --end_of_string, strr);
}
